It is fantastic to experience the sea, fjords and lakes in this region. The North Sea with its long white sandy beaches and huge crashing waves which are both fascinating and compelling and yet rough and scary at the same time. In contrast, the east coast is calm, peaceful and relaxing. The east coast is also indented by the beautiful Limfjord which offers a very special nature experience, including the local seal population. Last, but by no means least, the idyllic and undisturbed lakes of Tange and Madum are well worth a visit. Leso is famous for its large variety of sea depths and geological structure with stone reefs, bubbling chalk columns and coral reefs, which host a rich diversity of flora and fauna. The waters around Leso are home to blue lobsters, small sharks, seals, porpoises and large populations of resting water birds. The chalkland of Thy extends from Agger Tange in the south to Hanstholm in the north, and from the North Sea in the west to farming land in the east. It covers an area of 23,100 hectares, much of it barren, sandy and windswept along the coast. Most of the chalk moorland in Thy is relatively untouched. Sand dunes, sandy heaths, and sandy plants, plus a few lakes dot the area - such as Lake Nors, which is open to all visitors. Lille Vildmose and the Kattegat coast cover a total of 20,000 hectares. Here you will find the greatest concentration of wild boar in Denmark. The landscape is mainly made up of bogs, former stone age sea islands and coastal cliffs from the sea. The stone age sea extended across the whole of the eastern part of Himmerland and as the land rose and the sea receded, a shallow lagoon was created. Around 500 AD sphagnum mosses arrived, and moorland started to spread. Today the area is estimated to be the largest moorland in northern Europe. The moorland has poor flora due to low nutrient supply and consequently, there are only 12-15 different species besides the sphagnum mosses. In addition to these three exciting areas, the region has plenty more to offer nature lovers. For birdwatchers, there is the bird cliff at Bulbjerg. There is also the nature reserve of Vejlerne, which covers land reclaimed from the sea. The 6,000-hectare reserve is home to the biggest reedbeds in Denmark and some of the country's largest tidal meadows. The Hirsholmene nature reserve also boasts a remarkable bird population. The reserve is one of the most important resting places in Northwest Europe and an important breeding place for wildfowl.
